GENERAL INFORMATION



caution
  • The multi around monitor helps the driver recognise an obstacle. When you drive your vehicle, you must monitor the safety around your vehicle by yourself.
  • The number of occupied passengers or the quantity of remaining fuel may affect the guide lines on the display. This may lead to dimensional deviations. Therefore, you should use this system as only a guide.
  • The property of the camera lens (wide-angle lens) may cause the displayed image to be distorted or the displayed distances to deviate from the actual ones.
  • The camera is a precision device. It should not be exposed to strong impact such as high-pressure car washes. A malfunction may result.
  • To ensure the camera image is clearly visible, wipe the lens with a damped rag and then a dry rag to remove dust, rain drops or snow.
  • Be careful not to damage the camera lens. Any damage may have an adverse effect on the screen image.
The multi around monitor system consists of four cameras; front, rear and right/left sides (on outside mirrors). By using these cameras, the system displays front, rear and side views as well as bird’s eye-view (compound view) on the radio and CD player <vehicles with display audio>, multivision display <vehicles with MMCS>, or the inside rear view mirror assembly (with integrated monitor) * <vehicles without display audio and MMCS> to help the driver monitor the safety around the vehicle.
note *: The inside rear view mirror assembly (with integrated monitor) is also equipped with an automatic anti-dazzling function. For more information, refer to GROUP 52A - Inside Rear View Mirror.




Parts name
Functional description
Front-view camera
Is supplied with power through the camera-ECU, and sends a camera image to it.
Rear-view camera
Side-view camera (LH), (RH)
Camera switch (integrated in the steering wheel audio remote control switch)
Sends a camera switch signal through the radio and CD player <vehicles with display audio>, multivision display <vehicles with MMCS> to the camera-ECU.
Steering wheel sensor
Informs the ETACS-ECU of a steering wheel angle.
Camera-ECU

  • Receives various signals from the ECUs via CAN.
  • Overlays a guide line on a camera image, and sends it to the radio and CD player <vehicles with display audio>, multivision display <vehicles with MMCS> or the inside rear view mirror assembly (with integrated monitor) <vehicles without display audio and MMCS>.
  • Receives a camera switch signal from the radio and CD player <vehicles with display audio>, multivision display <vehicles with MMCS> or the inside rear view mirror assembly (with integrated monitor) <vehicles without display audio and MMCS> and switches the camera images.

Inside rear view mirror assembly (with integrated monitor)

  • Incorporates a monitor at the left side, and displays a camera image on it by receiving a camera image signal from the camera-ECU.
  • Incorporates a camera switch and sends a camera switch signal to the camera-ECU by pressing the camera switch.

Radio and CD player <Vehicles with display audio>

  • Radio and CD player receives camera image output request signal from the camera-ECU.
  • Radio and CD player receives camera image signal from the camera-ECU, and displays a camera image on the screen.

Multivision display, CAN box unit <Vehicles with MMCS>

  • MMCS receives camera image output request signal from the camera-ECU through the CAN box unit.
  • MMCS receives camera image signal from the camera-ECU, and displays a camera image on the screen.

ETACS-ECU
Informs the camera-ECU of the ignition switch status, the steering wheel angle, the selector lever position, the vehicle speed signal, the back-up lamp status and the vehicle condition.
Engine-ECU
Informs the ETACS-ECU of the vehicle speed.
ASC-ECU
Sends a vehicle speed signal to the engine-ECU.
Diagnosis connector
Is connected to M.U.T.-III to read the diagnosis code and service data associated with the camera-ECU.
Inhibitor switch
Informs the ETACS-ECU of the selector lever position.

Screen transition


Screen transition will progress in accordance with the camera switch signal, which radio and CD player <vehicles with display audio> or multivision display <vehicles with MMCS> receives from the camera switch, your operation of the camera switch, which is integrated in the inside rear view mirror assembly <vehicles with out display audio and MMCS>, OFF request signal (by display audio or MMCS), the selector lever operation and vehicle speed signal as follows:





Function



Bird’s eye-view function




The camera-ECU processes four camera images and stitches them together to realise a bird’s eye-view.

Front-view function




A vehicle width guide line and a distance guide line are overlaid on the front-view camera image.

Rear-view function




A vehicle width guide line and a distance guide line are overlaid on the rear-view camera image.

Side-view function




A vehicle width guide line are overlaid on the side-view camera (RH) image.

Expected driving path display function




Displays a driving path, which is expected in accordance with the steering wheel angle.

Language setting <Vehicles without display audio and MMCS>


Selects an interface language, which is displayed on the warning notice area, in accordance with a language selection signal sent by the combination meter.

Dimmer function <Vehicle without display audio and MMCS>


Reduces the brightness of vehicle icons or others not to interfere with the driver’s vision at night (When the position lamps illuminate).

Fail-safe function



The camera-ECU always monitors its own status and the camera signals. If the ECU detects a failure, it will set a diagnosis code and display a message to alert the driver.
